A lens is mounted to the lower surface of the panel for enclosing the light-emitting section of the lamp. The panel preferably has a pair of oppositely directed pivot members which are adapted to engage with inwardly directed flanges of the canopy fixture housing to removably and pivotally support the panel for movement between a vertical, inoperative position and a horizontal, operative position.
